python - 使用 print() 截断长字符串

Question

我尝试了以下代码

s='Python is an interpreted high-level programming language for general-purpose programming. Created by Guido van Rossum and first released in 1991, Python has a design philosophy that emphasizes code readability, notably using significant whitespace. It provides constructs that enable clear programming on both small and large scales'
s1='Python features a dynamic type system and automatic memory management. It supports multiple programming paradigms, including object-oriented, imperative, functional and procedural, and has a large and comprehensive standard library'
print(s,end='\r')
print(s1)

我得到的输出是

Python is an interpreted high-level programming language for general-purpose programming. Created by Guido van Rossum and first released in 1991, Python has a design philosophy that emphasizes code readability, notably using significant whitespace. It provides con
Python features a dynamic type system and automatic memory management. It supports multiple programming paradigms, including object-oriented, imperative, functional and procedural, and has a large and comprehensive standard library

第一个字符串s打印在两行上。\r然后从第二行开始打印第二个字符串。

我希望从第一个字符串的开头打印第二个字符串。是否可以使用print或应该使用任何其他功能？

这是您正在使用的终端仿真器的一项功能。是的，您可以使用 print 来执行此操作，您需要为您的终端类型输出适当的终端转义序列。

例如，如果您在类似终端仿真器的 xterm 中，转义序列在此处描述（该页面用于 bash，但 python 的语法非常相似）。您可能最感兴趣的转义序列是：

• 保存光标位置：\033[s
• 恢复光标位置：\033[u

如果您正在做一些更复杂的事情，您可能还会对curses库感兴趣。
